TIN-PLATE POLSHING AND CLEANING MACHNE.

Application filed .Tune 30, 1922.

To all whom t may concern:

Be it kown that we, JAMES E. KANE and ARTHUR J. Maenner, J r., citizensof the United States, residing at Canton, in the county of Stark andState of Ohio, have `invented a new and useful Tin-Plate Polishing andCleaning Machine, of which the following is a specification.

This invention relates to tin plate polishing and cleaning machines andhas for its objects to improve the construction of machines of this typesuch as are now in general use; to provide an improved conveyer for thebran, which is so constructed that an auxiliary cleaning machine may becoupled to the usual cleaning machine without requiring more additionalspace than is necessary to accommodate the auxiliary machine; and toprovide means for evenly distributing the bran vupon the cleaning andpolishing rolls.

The above and other objects may be attained by constructing the machineas illustrated in the accompanying drawings, in which* Figure 1 is alongitudinal sectional view through a machine embodying the invention,showing an auxiliary machine coupled thereto;

Fig. 2, a section on the line 2-2, Fig. 1; and

Fig. 3, a section on the line 3-3, Fig. 1.

Similar numerals refer to similar parts throughout the drawings.

Referring to Fig. 1, the main cleaning machine is indicated generally at1, the auxiliary machine is indicated generally at 2, and is constructedsubstantially like the main cleaning and polishing machine, exceptingthat fewer rolls are provided in Jche auxiliary machine.

It has been found in practice that tin sheets cannot be entirely cleanedby passing them through one bran and for this purpose, an auxiliarymachine is usually coupled to a larger cleaning machine in order thatthe sheets may be passed through the bran in the auxiliary machine totake 0E the greater amount of grease, after which they are furthercleaned and polished in the larger machine.

With the type of conveyers provided upon cleaning and polishing machinesnow in general use, considerable additional space is required to attachan auxiliary machine to the large cleaning and polishing ma- Sciial No.571,910.

chine, and in shops where a great number of cleaning machines are usedand the iloor space is limited, it is impractical lto attach auxiliarymachines to all of the cleaning and polishing machines in the shop.

lVith the present form of conveyer, the auxiliary machine may beattached to the large machine without requiring any space additional tothat actually taken up by the auxiliary machine, as the conveyer is sopositioned'that it does not extend beyond the' end of the machine,permitting the auxiliary machine to be placed in close proximitythereto.

The large machine and the auxiliary machine are each provided with theside frames 3 supported upon legs l and each lhas at its rear end a pairof 'curved lguide plates 5 and 6, a rear wheel 7 extending from theupper guide plate 5 to the top of the side walls 3.

Referring now to the auxiliary machine, as each sheet A is passedbetween the guide plates 5 vand 6, it is received between a pair ofrolls 8 and 9, ythe upper roll 8 being driven at a greater speed thanthe lower roll 9, causing the sheet to move forward through the machineat the speed of the lower roll. while the upper roll cleans the uppersurface of the sheet.

This cleaning is accomplished with bran or the like contained in thehopper 10 which is downward and rearwardly inclined and communicates atits lower end with the horizontally disposed tube 11. The tube 11 isconnected at opposite ends with elbows 12 and 13 to which are connectedthe vertical tubes 14C and 15 respectively.4 Elbows 16 and 17respectively are connected to the upper ends of the tubes 14 and 15,said elbows being connected by a member comprising the tubular endportions 18 and the `central cut away portion consisting of the spacedbarsor plates Sprocket wheels 2O are mounted in the elbows 12, 13, 16.and 17, one of the sprocket wheels being driven as by the gear 21. Anendless sprocket chain 22 is located through the tubes and over all ofsaid sprockets and provided at intervals with the cups 23. The underside of the chain 1s provided with the half round projections Y 24 whichenga-ge the roller 25 suspended upon the depending arms 26 carried uponthe side plates 19, tending to give the chain a vibrating motion as itpasses between the plates 19, shaking all of the bran 'from the cups 23.

The bran thus carried up `trom the hopper l0 is deposited between theupper roll 8 and the double auger 27 which spreads the bran evenly alongthe entire length oi the roll 8. The inner end or" the curved guideplate 6 is provided with the depending portion 28 having the forwardlydisposed flange 29 terminating beneath the center oi? the lower roll 9,

Spaced from the rolls 8 and 9 is a similar pair of rolls 30 and 3l whichreceive the sheet from the rolls 8 and 9, an inverted V-shaped plate 32being located between the rolls 9 and 3l. A similar pair of rolls 33 and34 is spaced forward of the rolls 30 and 3l, a V-shaped plate 32 beinglocated between the rolls 3l and 34:.

All of the cleaning and polishing rolls above described and the doubleauger 27 are geared in any suitable and well known manner to be drivenby a suitable power means in the direction of the arrows shown inl Fig.l.

A transverse bar 35 is mounted between the side walls 3 of the auxiliarycleaner and provided with forwardly extending fingers 36 located in aline to receive the sheets as they pass from the cleaning and polishingrolls, a brush 37 being mounted above the fingers in position to wipethe upper 'faces of the sheets as they are passed over the fingers,

As the sheets pass from the auxiliary cleaner, they are carried betweenthe guide plates 5 and 6 of the large cleaning machine and pass throughthe cleaning and polishing rolls 8a and 9a, 30a and 3l, 332L and 34E,33b and 34h which are arranged similar to the cleaning rolls of theauxiliary machine.

A double auger 27a is arranged adjacent to the roll 8a and operates inthe saine manner as the auger 27 to spread the bran evenly along theentire length of the roll 8a. A hopper l()a is provided beneath t-hecleaning and polishing rolls of the large machine and communicates withthe tube ll of the auxiliary machine, said tube being a. partl of aconveyor identical to the conveyer above described in connection withthe auxiliary machine, the same reference numerals being applied in thedrawings to similar parts,

The lower curved guide plate of the large machine is provided with adepending portion 28"L and a forwardly disposed flange 29"1L extendingto a point beneath the center of the roll 9a. V-shaped plates 32a arelocated between the lower rolls 9a, 31a, 34a and 34e, these platesretaining the bran between the lower cleaning and polishing rolls of thelarge machine in the saine manner as the plates 32 of the auxiliarymachine. A delivery roll 38 is located at the delivery end of the largemachine in position to receive the sheets from the cleaning andpolishing rolls, a brush 39 similar to the brush 37, being located abovetrie delivery roll in position to wipe the upper face of the sheet as itpasses over the delivery roll,

All of the feed rolls, the delivery roll and the double auger of thelarge machine are provided with suitable gearing by means ot which theyare driven in the directions of the arrows shown in Fig. l. The cleaningand polishing rolls of the auxiliary and large machines are botharranged to be driven in the same manner, alternate upper and lowerrolls being driven at a fast speed,

while the coasting rolls are driven at a slow speed, the sheet takingthe speed of the slow rolls, while the fixed rolls tend to clean andpolish the -suri'aces oi the sheet, F or instance, in the auxiliarymachine, the rolls lows: The sheets are passed from the tin pot into theauxiliary machine, as shown in Fig. l, all of the rolls of the twomachines being operated in the directions indicated in said ligure. Theconveyers are driven in the direction of the arrow shown in Fig. 2,carrying the bran upward from the hoppers l0 and l0, and depositing thesame between the double angers 27 27 and the cleaning and polishingrolls S-Bf The flanges 29 and 29a and the V-shaped plates 3.2 and 32Lretain the bran between the lower cleaning and polishing rolls, while aconsiderable amount of the bran is carried forwardly upon the sheet, thecleaning and polishing rolls working at two speeds, removing the greasefrom the surfaces of the sheets and polishing the saine, while thebrushes 3i and 39 remove the surplus bran from the upper surfaces of thesheets, permitting the same to drop back into the hoppers. n

The greater amount ot' grease and dirt is removed from the sheets asthey pass through the auxiliary machine and as the sheets ent-er thelarger machine, they are passed through a second bran which iscomparatively clean, removing any slight remaining grease and polishingthe Surfaces ot the sheets as they pass through the larger machine.

lWith the construction of conveyer illustrated and described in thisapplication, no additional room is required for the conveycrs and theauxiliary machine may be butted against the larger machine, permittingthe machines to be coupled together with the use of a minimum amount ofroom.
